Its on the homepage www.euronaut.org than "Technische Daten"

Normal operating depth = 250 m (820 feet)
Test depth             = 320 m (1050 feet)
Collapse depth greater = 500 m (1640 feet)

Speed surface about 8 kn, submerged about 5 knots. (1kn = 1 seamile/h) 
Max. horsepower(engine) on the surface 195 HP, underwater about 55 hp.  

Tomorrow I will pressure the diver chamber unmanned 
down to about 100 m (330 feet). If everthing is fine we can do some
manned test "dives" to 67 m (220 feet). 

best regards Carsten
